Abstract

Perfeccionamientos introducidos en las juntas eléctricas de separación de dos circuitos de vía principales adyacentes, aguas arriba y aguas abajo, con relación al sentido del tráfico, de un sistema de señalización ferroviario, utilizando los carriles como conductores, circuitos recorridos, respectivamente, por señales eléctricas de una primera frecuencia aguas abajo y de una segunda frecuencia aguas arriba, estando limitada dicha junta, en sus extremos, respectivamente, por bloques de sintonización aguas abajo, sensible a dicha primera frecuencia aguas abajo, y que ofrece una impedancia reducida a dicha segunda frecuencia aguas arriba, y una impedancia capacitiva a dicha primera frecuencia aguas abajo, y por un bloque de sintonización aguas arriba.
